A tow bar (10) is disclosed which has first and second arms (34, 40) mounted on a member (16) on the towing vehicle (12). The arms can vary in length between a shortened storage configuration, where they are secured to the first member; to a lengthened towing configuration where they are attached to a second member (70) attached to the towed vehicle (14). The arms are attached to the members for pivotal motion about vertical axes. The arms themselves have horizontal pivot hinges near each end thereof and a hinge permitting each arm to twist. The tow bar provides for efficient backing.
